Excellent for construction or renovation projects. Use on your mound, batter’s box and catcher’s box. These revolutionary mound clay blocks are the typical brick size, but they are parallelogram shaped with 10° angled sides that run the length of the block. When laid properly, the angled sides overlap and compact more easily into one solid mass. The blocks are made of extruded, unfired red gumbo clay. Packaged in bags of 8 blocks in order to protect the blocks from drying out
